Cautions in Using with Safety

Fundamental Matters of “WARNING!” and “CAUTION!”

WARNING!

Do not use this unit in an area where there is flammable or explosive gas

Never use this unit in an area where there is flammable or explosive gas.

This unit is not explosion-proof. An arc may be generated when the power switch is turned on or off,

and fire/explosion may result. (Refer to page61 “List of Dangerous Substances”.)

Always ground this unit

Always ground this unit on the power equipment side in order to avoid electrical shock due to a power

surge.

If a problem occurs

If smoke or strange odor should come out of this unit for some reason, turn off the power key right

away, and then turn off the circuit breaker and the main power. Immediately contact a service

technician for inspection. If this procedure is not followed, fire or electrical shock may result. Never

perform repair work yourself, since it is dangerous and not recommended.

Do not use the power cord if it is bundled or tangled

Do not use the power cord if it is bundled or tangled. If it is used in this manner, it can overheat and

fire may be caused.

• Connect the power plug to a receptacle with grounding connectors.

• Do not forget to ground this unit, to protect you and the unit from electrical shock in case of

power surge. Choose a receptacle with grounding connectors as often as possible.

• Do not connect the grounding wire to a gas pipe, or by means of a lightning rod or telephone

line. A fire or electrical shock will occur.

2. Choose a proper place for installation

• Do not install this unit in a place where:

♦ Rough or dirty surface.

♦ Flammable gas or corrosive gas is generated.

♦ Ambient temperature exceeds 35°C.

♦ Ambient temperature fluctuates violently.

♦ There is direct sunlight.

♦ There is excessive humidity and dust.

♦ There is a constant vibration.

• Install this unit on a stable place with the space as shown below.

Main Unit

More than

50cm

More than

50cm

More than 20cm

Front side

3. Do not use this unit in an area where there is flammable or explosive gas

• Never use this unit in an area where there is

flammable or explosive gas. This unit is not

explosion-proof. An arc may be generated

when the power switch is turned ON or OFF,

and fire/explosion may result. (Refer to page

61 “List of Dangerous Substances”.)

Before Using this unit

Requirements for Installation

4. Do not modify

• Modification of this unit is strictly prohibited. This

could cause a failure.

5. Installation on horizontal surface

• Set this unit to the flattest place. Setting this

unit on rough or slope place could cause the

vibration or noise, or cause the unexpectible

trouble or malfunction.

6

Before Using this unit

Requirements for Installation

CAUTION!

6. Choose a correct power distribution board or receptacle

• Choose a correct power distribution board or receptacle that meets the unit’s rated electric

capacity.

Electric capacity: IU400: 100V AC (Single phase), 13A

IU800: 100V AC (Single phase), 14.5A

NOTE)

There could be the case that the unit does not run even after turning ON the power. Inspect

whether the voltage of the main power is lowered than the specified value, or whether other

device(s) uses the same power line of this unit. If the phenomena might be found, change the

power line of this unit to the other power line.

7. Before/after installing

• It may cause injure to a person if this unit falls down or moves by the earthquake and the

impact. etc.. To prevent, take measures that the unit cannot fall down, and not install to busy

place.

8. Handling of power code

• Do not entangle the power cord. This will cause overheating and possibly a fire.

• Do not bend or twist the power cord, or apply excessive tension to it. This may cause a fire

and electrical shock.

• Do not lay the power cord under a desk or chair, and do not allow it to be pinched in order to

prevent it from being damaged and to avoid a fire or electrical shock.

• Keep the power cord away from any heating equipment such as a room heater. The cord's

insulation may melt and cause a fire or electrical shock.

• If the power cord becomes damaged (wiring exposed, breakage, etc.), immediately turn off the

power at the rear of this unit and shut off the main supply power. Then contact your nearest

dealer for replacement of the power cord. Leaving it may cause a fire or electrical shock.

• Connect the power plug to the outlet which is supplied appropriate power and voltage.

9. Setting shelf

• Do not use other shelf than specified one. Failure to do so could cause the malfunction of the

temperature control.

• Set the specific shelf plate(s) to the appropriate shelf pole, and use it (them).
